In reading about for more information on Bingley's post regarding diaetetic, I came across this largely unrelated term:
atretic
"Having an abnormal closure or absence of a body opening or tubular organ (for example, a child born without an oesophagus would have an atretic birthdefect). "
*Note the spelling of oesophagus; I would spell it 'esophagus,' but perhaps this is a regional difference.

Dear WW: atresia is not a rare condition. I still remember being told in embryology that every newborn baby should have little finger of obstetrician very cautiously inserted into its rectum to detect imperforate anus. An excess of caution. Little girls may have imperforate hymen,but that is seldom troublesome and easily corrected. Embryology is fascinating. There are so many changes made so rapidly that it is amazing that there are not far more congenital defects.

What is an imperforate anus, wwh? Is it one through which that which would be expelled cannot be?

Exactly. Embryology is fascinating in the way many structures are formed. It has been so long since I studied it that I can't describe the steps in which the tube that is the intestinal tract which is I guess endoderm,with a bind end, meets the skin, which is ectoderm, and for quite a while the opening is closed by a layer of both, then a rim forms, and the opening is formed. We are strangely and wonderfully made. I'd be surprised if there were any pictures of this on the Internet, but I'll look.

Here's some picture about spina bifida, a potentially tragic failure of developing lower end of spine with spinal cord inside to become separate from the skin. You can get some ideas of the layers forming. There are so many such events it is a marvel that congenital anomalies are not far commoner than they are.

You forgot to post the link, wwh. Thanks for doing so if you can find it again.

Dear WW: I came back and edited it in.Can't understand what happened. I'll try to find the site again, Think I can. Actually, I blocked on name of the problem, and had to search for approximations of the problem before I found it. Spina bifida. It's been a long time since I saw a patient with it.Anyhow here's the URL: http://www.pediatric-orthopedics.com/Topics/Embryo_S_Bifida/embryo_s_bifida.html
"Select" it, press Control,C, then put insertion point into Location Box, and press Contro, V That should do it.

Has spina bifida got less common over the years? I remember back in the 1970s one of our neighbour's kids had had surgery for this problem, and spina bifida used to feature quite regularly in the medical sections of newspapers and on TV, but I haven't heard anybody mention it for years.

Thanks, wwh.
Bingley, I haven't heard anything regarding spina bifida's having become less common. I'd be interested in knowing whether there has been a decrease.

Dear WW: I would doubt that there would be any likelihood of a change in incidence of spina bifida. A lot of congenital anomalies may be associated with mother having virus infection such as rubella during third month of pregnancy. I don't recall reading that spina bifida is in that group. Nor have I read that it is familial. But I haven't read much about it. Remember that many "changes" in incident of any disease may be just a change in recognition and reporting of diseases.
